Explanation:
The kingdom of Kerma grew wealthy from agriculture and the mining of gold. Trade (gold, precious stones, ivory, animal hide, ebony, cattle) also contributed to the city's wealth, due to its location in the centre of a fertile basin and at the crossroads of desert routes linking Egypt, the Red Sea and the heart of Africa.
